If two alleles generate a heterozygote phenotype that is intermediate between the homozygotes for each allele, the alleles are said to exhibit
A) complete dominance.
B) incomplete dominance.
C) recessive characteristics.
D) blending.

Question

Quizplus · Accepted Answer

Incomplete dominance is when the heterozygote phenotype is a blend or intermediate between the homozygous phenotypes. This is in contrast to complete dominance, where one allele completely masks the expression of the other, and blending, which is not a genetic concept. Recessive characteristics refer to the expression of a trait only in homozygous individuals, and do not necessarily have anything to do with incomplete dominance.
